- Acrylic
- Thermoplastic glazing material.
- Aerogel
- A microporous, transparent silicate foam currently under development for potential use as a glazing cavity-fill material, offering very high thermal performance.
- Air infiltration
- The amount of air leaking in and out of a building through cracks in walls, windows, and doors.
- Airspacer
- Component placed at the perimeter of an insulating glass unit to separate the two lites of glass.
- ANSI
- American National Standards Institute, a clearinghouse organization for all types of standards and product specifications.
- Architectural Windows
- Custom-designed windows that enhance the aesthetic appeal of a building, often featuring unique shapes and sizes.
- Double Hung Windows
- Windows with two vertically sliding sashes, allowing both the top and bottom halves to open for ventilation.
- Entry Doors
- Main doors providing access to a building, designed for security and curb appeal.
- Fabric Storm Panels
- Lightweight, fabric-based panels used for hurricane protection, offering an alternative to traditional metal shutters.
- Horizontal Sliding Windows
- Windows that open by sliding horizontally, typically featuring one fixed pane and one movable pane.
- Metal Storm Panels
- Removable panels made of aluminum, steel, or clear polycarbonate, used to protect windows and doors during hurricanes.
- Patio Doors
- Large doors, often sliding or hinged, that provide access to outdoor spaces like patios or decks.
- Replacement Doors
- New doors installed to replace existing ones, improving energy efficiency, security, and aesthetics.
- Replacement Windows
- New windows installed to replace old or damaged ones, enhancing energy efficiency and appearance.
- Storm Protection
- Measures and products designed to safeguard buildings from severe weather conditions, such as hurricanes.
- Tempered glass
- Glass heat-treated to withstand greater than normal forces on its surface. When it breaks, it shatters into small pieces to reduce hazard.
- Tenon
- A rectangular projection cut out of a piece of wood for insertion into a mortise.
- Thermal break
- A thermally insulating or low-conductance material used between interior and exterior aluminum (or other conductive material) window and door components.
- Tilt window
- A single- or double-hung window whose operable sash can be tilted into a room to allow cleaning of the exterior surface on the inside.
- Transom
- Window used over the top of a door or window, primarily for additional light and aesthetic value.
- Triple glazing
- Use of three panes of glass or plastic with two airspaces between. Generally refers to a sealed insulating unit.
- True divided lites (TDLs)
- Traditional window construction incorporating smaller panes of glass actually separated by muntins, rather than simulating such an appearance with larger lites of glass and a muntin grid or grille placed between or on the surfaces of the glass layers.
- U-factor
- Rate of heat flow-value through a building component, from room air to outside air. Also referred to as U-value. The lower the U-factor, the better the insulating value. U-factor, a rating more generally used in the window industry, is the reciprocal of R-value, a rating commonly used in the insulation industry.
- Ultraviolet light (UV)
- Invisible rays that are part of the energy that comes from the sun, which can cause fading and deterioration of materials.
- Vinyl
- Generic term for polyvinylchloride or PVC, an extruded material used for window and door framing.
- Warm-edge
- A type of insulating glass construction using an airspacer offering lower thermal conductance than traditional aluminum spacer. Warm-edge IG units typically offer higher resistance to condensation and an incremental improvement in window energy performance.
- WDMA
- Window and Door Manufacturers Association. Formerly the National Wood Window and Door Association, this trade organization has established many standards related to wood window and door products.
- Weatherstripping
- A material or device used to seal the openings, gaps or cracks of venting window and door units to prevent water and air infiltration.
- Weld
- A term used for a type of corner construction, used with vinyl and other types of windows and doors, in which a small amount of material at the two pieces are melted or softened, then pushed together to form a single piece. This also is referred to commonly as a fusion-weld.
- Wildland / Urban interface
- An area where buildings are bounded by wild or natural areas in regions where wild fires are a concern. Some fire and code officials are looking at the establishment of fire-resistance requirements for exterior building products in these "interface" areas.
- Wind Load
- Force exerted on a surface by moving air.
